Researchers from the University of Twente and the Institute of Technology in The Netherlands recently announced that they've manufactured a microchip that can harvest its own energy.
They placed efficient solar cells made from amorphous silicon or copper indium gallium selenide (CIGS) on top of a microchip, layering the solar cells to each layer of the chip; this process uses fewer materials, and ultimately performs better. After layering the solar, cells, the result was a sensor chip that included harvesting intelligence and an antenna for wireless communication.
Researchers found that the chip could effectively produce its own energy from its surroundings even in low light. They also noted that as long as the chip's energy was below 1milliwatt, it could even be operated indoors.
